OpenSSL

Please install openssl on your system.

brew install openssl@1.1

Then pin this version:

brew pin openssl@1.1

Note that a LibreSSL-based version of openssl is typically pre-installed on macOS. We do not want to use this version since it may have issues dealing with environment variables in the openssl configuration files. To make sure that the Homebrew-installed version is used instead of the pre-installed version, add the following line to your bash profile or the equivalent. (vi ~/.zshrc)

export PATH=$(brew --prefix)/opt/openssl@1.1/bin:$PATH
